Description

Technical Field

[0001] The present invention relates to the technical field of gyroscope testing equipment, in particular to a vertical gyroscope comprehensive tester. Background Art

[0002] The vertical gyroscope is a crucial aviation navigation device, providing an attitude reference for aircraft. With the advancement of aviation technology, the performance testing requirements for vertical gyros are becoming increasingly stringent, requiring more precise and efficient testing equipment. Currently, vertical gyroscope testing is primarily performed using specialized testers, which typically include a turntable, power supply, and measuring instruments.

[0003] However, existing vertical gyroscope testing equipment has the following problems: First, each step of the test requires manual operation by the operator, which is cumbersome. For example, checking the unlocking time and the gyroscope start time requires manually starting the timer, observing the signal light, and recording the time. Second, the overall test is cumbersome and the time sequence is highly logical. The operator must be proficient in the entire test process, and it is easy to make operational errors that lead to test interruptions. Third, the overall test time is long and the efficiency is low. Fourth, two turntables are required to complete all tests (one turntable completes the swing, angular velocity rotation and other functions, and the other manual turntable completes the tilt angle setting). The turntable needs to be replaced during the test, which is cumbersome.

[0021] Figure 1 It is a structural schematic diagram of a vertical gyroscope comprehensive tester provided by an embodiment of the present invention.

[0022] like Figure 1 As shown, the vertical gyro comprehensive tester provided by the embodiment of the present invention may include a turntable 10, a control console 20 and a test platform (not shown in the figure).

[0023] In a specific implementation process, the turntable 10 may include a programmable electric swing turntable 101 and a programmable tilt turntable 102. The programmable electric swing turntable 101 is driven by a high-precision servo motor. The main performance indicators of the programmable electric swing turntable 101 are as follows: (1) Angular velocity range: 0.01° / s~400° / s; (2) Table runout: The runout of the table at the end face with a diameter of 300mm shall not exceed 0.5mm; (3) Angular rate accuracy: At 20℃±5℃, when the angular rate is 0.01° / s~10° / s, the accuracy is ±3%; when the angular rate is 10° / s~400° / s, the accuracy is ±1%; (4) Tilt angle error: The rocking turntable 10 can achieve a rocking motion with a tilt angle of 0° to 10°, with a tilt angle error of no more than ±0.5°. The tilting turntable 10 can be continuously programmable and adjustable with a tilt angle of at least 0° to 20°, with a tilt angle error of no more than ±0.1°.

[0024] (5) Zero return error: The zero return error of the turntable 10 is not greater than ±0.2°.

[0025] (6) Load-bearing capacity of turntable 10: When the load of turntable 10 in the rotation test is not more than 15kg, it meets all performance requirements. When the load of turntable 10 in the swing test is not more than 12kg, it meets all performance requirements.

[0026] (7) Dimensions and weight of the detector: Dimensions: not more than 350×350×430mm. Weight: not more than 45kg.

[0027] In one specific implementation, programmable tilt table 102 is mounted on the top platform of programmable electric swing table 101, secured with high-strength bolts to prevent relative displacement during testing and eliminate the need for disassembly. Programmable tilt table 102 offers continuous programmable adjustment of at least 0-20° inclination, and a range of 0 to 90°. It can also be manually rotated 90° within a plane, enabling simulation of the tilt and pitch angles of certain gyroscopes.

[0028] The performance indicators of the programmable tilt table 102 may include: (11) Tilt angle error: The tilting turntable 10 can be continuously programmable and adjustable to a tilt angle of at least 0 to 20°, with a tilt angle error of no more than ±0.1°. The tilting turntable 10 can be programmable and adjustable to a tilt angle of 0 / 90°, with a tilt angle error of no more than ±0.5°.

[0029] (12) Zero return error: The zero return error of the turntable 10 is not greater than ±0.2°.

[0030] (13) Load-bearing capacity of turntable 10: When the load of turntable 10 is not less than 10kg during the rotation test.

[0031] Figure 2 It is a structural block diagram of the control console 20, such as Figure 2 As shown, the control console 20 includes an integrated display and control unit, a power supply for the vertical gyro and angular rate gyro, a programmable voltage and current meter and millivoltmeter (such as a programmable AC millivoltmeter) for data acquisition, and a relay board and solid-state relay for controlling signal on and off. The display and control unit can utilize a 21.5-inch touchscreen with a resolution of 1920×1080 and can be equipped with a common processor, memory, solid-state drive, and professional operating system. The power supply includes a power supply with multiple voltage output levels, including three-phase AC 36V, single-phase 36V excitation voltage, DC 27V, and DC 12V, required for the operation of certain vertical gyros and angular rate gyros.

[0032] The programmable voltage and ammeter can have a 6.5-digit display accuracy, a voltage measurement range of 0-100V, an accuracy of ±0.01%, and a current measurement range of 0-10A with an accuracy of ±0.02%. The millivoltmeter has a measurement range of 0-1000mV and an accuracy of ±0.005%. It is used to measure tiny voltage signals, such as the voltage values ​​of the tilt and pitch angle signals output by certain types of vertical gyroscopes and angular velocity gyroscopes. The relay board contains 16 mechanical relays, each rated at 10A. The solid-state relay uses optocoupler isolation technology with a response time of less than 1ms, and is used in high-frequency switch control scenarios. Among them, the tester controls the detection switch through the display and control all-in-one machine and the control keyboard, and uses the RS485 bus to automatically read the voltage meter and ammeter measurement data, and control the on and off of the signal through the relay board and solid-state relay.

[0033] In a specific implementation process, you can Figure 2 Disassembly instructions: First level: basic support layer (power supply + hardware execution): Power supply module: AC / DC27V power supply, AC / DC power supply provides power to the entire system and ensures power input to hardware such as relay boards and solid-state relays.

[0034] Relay / Solid State Relay: As an "electrically controlled switch", it receives upper-level control signals to realize circuit on-off (such as controlling the power supply of the device under test and switching the measurement circuit), and is the core component of hardware execution.

[0035] The second level: signal acquisition and conditioning layer: Measuring instrument cluster: The programmable AC voltmeter / current meter, programmable DC voltmeter / current meter, and programmable AC millivoltmeter (which can be an AC millivoltmeter) are responsible for collecting electrical parameters (voltage, current, and millivolt-level signals); the USB oscilloscope specializes in waveform observation (such as transient signals and distorted waveforms), covering "steady-state + dynamic" signal measurement needs.

[0036] Signal conditioning module: Filters, amplifies, and attenuates the original external input signal (which may contain noise or abnormal amplitude) and outputs a "clean, acquisition module-compatible" signal to ensure data accuracy.

[0037] The third level: control and processing layer: Intelligent Control Unit: This integrates data acquisition, logical analysis, and command output, serving as the system's "brain." It receives commands from the integrated display and control unit, actuates relays, and controls measuring instruments. It also aggregates collected data and performs computational processing (such as power conversion and harmonic analysis).

[0038] All-in-one display and control machine: It serves as both an operation terminal (sending control commands through the interface, such as setting the voltage range and starting measurement) and a display center (presenting measurement data, waveforms, and status alarms in real time), realizing a "closed loop of human-computer interaction."

[0039] The fourth level: communication and interaction layer: System interface: As an "external bridge", it realizes high-speed data transmission through the 100M Ethernet port (such as uploading batch measurement data to the host computer for analysis), is compatible with traditional equipment communication through the RS485 serial port (such as connecting to old controllers and debugging terminals), and supports "local control + remote collaboration" dual mode.

[0040] It should be noted that the control keyboard, control console 20 switch, TC6 power switch, TSZ-1 power switch, fuse, excitation A' phase, excitation A' neutral line, TSZ-1 interface, TC-6 interface, debugging test port, metering switch / interface, etc. involved in the figure are all commonly used components, as well as components that need to be connected and used during the experiment, and will not be repeated here.

[0041] In a specific implementation process, the test platform is a software part, which can control the turntable 10 and the control console 20 through the display and control integrated machine to automatically complete the test of the vertical gyroscope and output the test results. Figure 3This is a schematic diagram of the test platform structure. Figure 3 As shown, the test platform can adopt a modular design, including a system configuration module, a test program module, a hardware resource driver module, a self-test and calibration module, and a resource information management module.

[0042] The system configuration module adapts to different test requirements through different configurations. Specifically, this module first parses and verifies the test requirements, generating structured requirement data. The requirement parsing process involves two phases: semantic analysis and syntactic analysis, converting test requirements described in natural language into structured data that the system can recognize. The verification process then checks the completeness, consistency, and feasibility of the requirements to ensure that the requirement data meets the system's processing capabilities.

[0043] In a specific implementation, the system configuration module can reason on the requirement data based on a pre-built knowledge graph to obtain multiple candidate test solutions. The knowledge graph contains specialized knowledge in the field of vertical gyro testing, covering information such as test indicators, test methods, and test equipment parameters, as well as the relationships between them. The reasoning process uses a combination of rule-based and case-based reasoning to search for matching test solutions in the knowledge graph based on the input requirement data, resulting in multiple candidate test solutions.

[0044] When screening multiple candidate test plans, the system configuration module will retain the candidate test plans that do not conflict, and after making a decision on any two candidate test plans that conflict, it will retain one of the two candidate test plans. Conflict detection is based on resource occupancy analysis and test process compatibility analysis. When two test plans need to occupy the same hardware resources at the same time or there is a logical conflict in the test process, the system will mark the two plans as conflicting plans. For conflicting plans, the system configuration module, based on the knowledge graph, takes each candidate test plan in any two candidate test plans as the starting point and the test indicator as the end point, and obtains the number of test indicators that each candidate test plan can reach. This process is implemented through a graph traversal algorithm, calculating the reachability from the test plan node to each test indicator node, and counting the total number of reachable test indicators. In this way, the test coverage of each candidate test plan can be obtained, where the more test indicators each candidate test plan can reach, the greater its test coverage, and the fewer test indicators each candidate test plan can reach, the smaller its test coverage.

[0045] In a specific implementation process, the test accuracy of each candidate test solution and the activity of each candidate test solution within a preset time period can also be determined. The test accuracy can be calculated based on historical test data, indicating the accuracy of the solution's results in past tests; the activity reflects the frequency with which the solution has been used in the recent period, with the preset time period typically set to 30 days. Based on the number of test indicators, the test accuracy, and the activity, the system configuration module determines the confidence level of each candidate test solution.

[0046] In a specific implementation process, the confidence calculation formula can be referred to as follows:

[0047] in, represents the confidence of the i-th candidate test solution, Indicates the number of test indicators that can be achieved by the i-th candidate test solution, Indicates the maximum number of test indicators in all candidate test schemes, and the number of test indicators is normalized by the first term. represents the test accuracy of the i-th candidate test solution, It represents the weight of the i-th candidate test plan at time t, which can reflect that "recent activity is more important". The time-weighted average activity can focus on recent performance, and in the time series, an average value that reflects the overall trend can be calculated to avoid the interference of outliers at a single time point. represents the activity of the i-th candidate test solution at time t, and the activity is normalized by the third term, Indicates the step length of the preset time period, The weight representing the number of test indicators, represents the weight of the test accuracy, Indicates the weight of activity.

[0048] After obtaining the confidence of each candidate test plan among any two conflicting candidate test plans, the candidate test plan with a larger confidence can be retained. When the confidence difference is less than 0.1, the system will prompt the tester to make a manual selection.

[0049] In a specific implementation process, after obtaining the retained candidate test solutions, the system configuration module can configure the test strategy corresponding to the test requirements based on the retained candidate test solutions. Among them, the test strategy includes test sequence, test parameter settings, resource allocation plan, and exception handling mechanism. The test sequence is determined based on the dependencies between test items to ensure that subsequent tests are executed only after the previous tests are completed; the test parameter settings include specific values ​​for parameters such as the turntable angle, angular velocity, and test duration; the resource allocation plan clearly defines the time and method of use of each hardware resource during the test process; and the exception handling mechanism defines the abnormal situations that may occur during the test and the corresponding handling methods.

[0050] In a specific implementation process, the test program module is configured to test the functions and performance of the object to be tested, as well as to perform fault diagnosis and isolation based on the test information of the object to be tested. Among them, the test program module can first obtain the identity information of the tester and complete the identity authentication through RFID card recognition or account password login. Based on the identity information of the tester, the system obtains the tester's current test task information and historical test behavior habits. The current test task information is extracted from the task management database, including the test object model, test items, test requirements, etc.; the historical test behavior habits are obtained by analyzing the tester's past operation records, including commonly used test parameters, interface layout preferences, operation sequence and other information.

[0051] Specifically, an appropriate interface template can be selected based on the type of the current test task; the tester's historical interface layout preferences can be analyzed to determine the position and size of controls in the interface template; candidate test information can be pre-populated based on the tester's historical fill data; and if an adjustment request is detected from the tester, the candidate test information can be adjusted to obtain the test information of the object to be tested. In this way, the generated interactive interface is divided into four main areas: test control area, parameter setting area, real-time data display area, and result analysis area. The tester can adjust the size and position of each area using custom buttons on the interface.

[0052] In a specific implementation, the test program module uses an interactive interface to obtain test information about the object to be tested. This information includes the vertical gyro model, serial number, test item selection, and test parameter settings. The system automatically pre-populates common parameters, such as standard test voltage and standard test angular velocity, which the tester can confirm or modify. For different vertical gyro models, the system automatically adjusts parameter ranges and default values ​​based on its built-in product database to ensure appropriate test parameters.

[0053] Specifically, after obtaining the tester's identity information, the test program module then retrieves the tester's current test task information and historical testing habits based on the tester's identity information. Based on this information, the test program module generates the tester's interactive interface, layouts the page according to the tester's testing habits and test task information, and automatically pre-populates data. This is achieved as follows: The system maintains a user preference database that records each tester's interface layout preferences, commonly used parameter settings, and operation sequence. When a tester logs in to the system, the system extracts the tester's preference data from the database and, based on the requirements of the current test task, generates a personalized interactive interface. Regarding interface layout, the system analyzes the tester's past operation records to identify the most frequently used functional areas and places them prominently in the interface. Regarding parameter pre-population, the system analyzes the tester's parameter settings used in similar test tasks and uses them as default parameters for the current test, or alternatively, generates default parameters based on the tester's past parameter settings. Regarding the operational process, the system adjusts the order of operational steps and prompts based on the tester's operational habits to better suit the tester's preferences. The tester can accept the pre-filled content by clicking the Confirm button on the interface, or modify it by clicking the Edit button. The system also provides a parameter validity check function. When the tester modifies the parameters, the system will check in real time whether the parameters are within the valid range and give corresponding prompts.

[0054] In a specific implementation, testers can double-click the product icon to enter the interactive interface, where they can access data such as the current test task type. Users can enter or modify test information, including "Tested Component Number," "Tested Component Extension Name," "Operator," and "Test Type," all of which will be displayed in the test report. After selecting the test, click Auto Test to begin the test process, automatically recording the collected data and analysis results.

[0055] In a specific implementation process, the hardware resource driver module drives the hardware resources to generate and collect test-related data. The hardware resources include multiple components of the turntable 10 and multiple components of the control console 20. The hardware resource driver module adopts a layered architecture design. The bottom layer is the hardware abstraction layer, which provides a unified hardware access interface; the middle layer is the device driver layer, which implements specific control of various types of hardware; the upper layer is the function interface layer, which provides a high-level function call interface to the test program module. For the control of the turntable 10, the driver module can accurately control the angle, angular velocity and acceleration of the programmable electric swing turntable 101 and the programmable tilt turntable 102; for the control of the control console 20, the driver module can set the power supply output parameters, configure the measuring instrument range, control the relay status, etc. During the data acquisition process, the driver module samples the voltage and current data at a frequency of 200Hz and the angle position data at a frequency of 100Hz to ensure that the time resolution of the test data meets the analysis requirements.

[0056] It's important to note that to ensure the software system's versatility, portability, and scalability, hardware resource driver development was dedicated to a separate module during the overall system software design. This module includes instrument resource drivers, serial / bus communication card drivers, and dedicated test card drivers. All hardware resource drivers were encapsulated twice or more to ensure independence from the test program.

[0057] In a specific implementation, the self-test and calibration module completes the self-test and channel calibration of the vertical gyro integrated tester and corrects the test results. The self-test process consists of two parts: hardware self-test and software self-test. The hardware self-test checks the connection status and basic functions of each hardware component, including the turntable 10 motor, encoder, power output, and measuring instrument; the software self-test verifies the integrity and communication status of each functional module. The channel calibration process uses standard source signals to calibrate the measurement channels, including the voltage channel, current channel, and angle channel. The voltage channel uses a standard voltage source with an accuracy of 0.001% for multi-point calibration to generate a calibration curve; the current channel uses a standard current source with an accuracy of 0.002% for calibration; and the angle channel uses an optical encoder and a high-precision angle standard for calibration. Test result correction is based on the calibration data. The calibration curve is applied to the original test data to correct it, eliminating the influence of systematic errors and improving the accuracy of the test results.

[0058] During a specific implementation, the resource information management module manages hardware resource configuration information, records tester operation information, and test results. Configuration information management includes the storage and maintenance of hardware resource parameter settings, calibration data, usage status, and other information. Operation information records include tester login information, operation sequences, parameter modification records, etc., supporting operation traceability and auditing. Test result management includes the storage, query, and export functions of raw test data and analysis results, supporting data export in multiple formats such as CSV, Excel, and PDF. The resource information management module also provides data backup and recovery functions, automatically backing up important data on a regular basis to ensure data security.

[0059] In a specific implementation process, the working principle of the above-mentioned vertical gyroscope comprehensive tester is as follows: the vertical gyroscope comprehensive tester only needs an external AC220V power supply to work. The control console 20 of the vertical gyroscope comprehensive tester provides a certain type of vertical gyroscope and angular velocity gyroscope with the three-phase AC36V AC power supply, single-phase 36V excitation voltage, and DC 27V power supply required for work, and measures the voltage values ​​of the tilt and pitch angle signals output by a certain type of vertical gyroscope and angular velocity gyroscope through a millivolt voltmeter.

[0060] A certain type of vertical gyroscope and angular velocity gyroscope are fixed on the turntable 10, and the tilt, pitch angle, angular velocity, etc. of the device are simulated by rotation and swing.

[0061] The equipment is convenient and simple to detect parts. You only need to connect the parts and wait for the equipment to start up. The equipment will automatically detect the parts under the control of software. The turntable 10 required for detecting a certain type of vertical gyroscope and TSZ-1 angular velocity gyroscope is in the equipment. There is no need to connect other turntables 10 externally. The turntable 10 is controlled by the tester itself and does not require human operation. After the test is completed, the test results are displayed on the equipment (unqualified test data are clearly marked).

[0062] Continue to see Figure 1To facilitate operator operation and testing, and to ensure the integrity of the equipment, the vertical gyro tester's control console 20 and turntable 10 are housed within a chassis 30, equipped with a front maintenance door. At least one sidewall of the chassis 30 is provided with heat dissipation holes. The vertical gyro tester can be constructed using a 19-inch chassis 30 with an overall height of 1.5 meters. The main technical parameters of the chassis 30 are as follows: Color: White (standard); Height: 1443.3mm; Internal Brackets: 30U; Depth: 500mm; Standard Accessories: a) Profile Frame: 1; b) Side Doors: 2; c) Top and Bottom Panels: 2 (flat bottom panel, load-bearing capacity: 40kg); d) Rear Door: 1; e) Front Door: 1; f) Fan: None; g) Casters: 4; h) Adjustable Feet: 4 (to secure the chassis 30 and adjust its level); i) Aluminum Brackets (L-shaped): 4. The equipment within chassis 30 utilizes a standard rack-mounted structure, making assembly and disassembly easy. When the tester's internal equipment needs to be removed for transport or use, all equipment can be quickly removed. The internal cables connecting the test equipment utilize quick-plug bayonet connectors, ensuring reliable connections and easy assembly and disassembly. The equipment is equipped with universal wheels for ground rollability.

[0063] In a specific implementation, the console 20 uses a standard 19-inch rack-mounted chassis 30 with dimensions of 440 mm × 480 mm × 310 mm (width × depth × height). The console 20 includes an operation area and an interface area; The operation area includes control buttons and / or touch components; the control buttons include a power switch, an emergency stop button, function shortcut keys and a numeric keypad. The buttons are backlit for easy operation in low-light environments. The touch components include a multi-touch screen and a touchpad, which support gesture operations to improve operating efficiency. The interface area includes a debugging and testing interface, a metering interface, an AC interface, an expansion interface, a USB interface, a vertical gyroscope interface and an angular rate gyroscope interface.

[0064] The test platform controls the turntable 10 and console 20 via an integrated display and control unit, automatically completing vertical gyro testing and outputting test results. The test platform software is developed using a hybrid C++ and Python framework. The core algorithm is implemented in C++ to ensure performance, while the interface and business logic are implemented in Python to improve development efficiency. The software architecture utilizes a microservices design, with functional modules communicating via standard interfaces to enhance system maintainability and scalability.

[0065] In a specific implementation, the relay board and solid-state relays are controlled by a display and control integrated device to simulate four states: lateral correction, longitudinal correction, on, and off. A programmable voltmeter and millivoltmeter are integrated into the output path to complete the correction current test. The relay control circuit uses an optoelectronic isolation design to prevent interference with signal transmission. In the lateral correction state, the system connects the correction signal to the lateral correction input of the vertical gyroscope via relay switching; in the longitudinal correction state, the system connects the correction signal to the longitudinal correction input. In the on state, all signal paths are connected; in the off state, all signal paths are disconnected. During the correction current test, a programmable voltmeter is connected in series in the correction signal path to measure the magnitude and waveform characteristics of the correction current; a millivoltmeter is connected in parallel in the correction signal path to measure changes in the correction voltage. Test data is recorded at a 10kHz sampling rate to ensure that rapidly changing signal characteristics are captured.
